Cleanrooms are the cornerstone of modern high-end manufacturing, and the stability of their air cleanliness directly determines product yield, safety, and compliance. HEPA /ULPA filters, as the “precision lungs” of cleanrooms, require a selection process that goes far beyond a simple efficiency numbers game. As your air filtration solutions partner, Trenntech understands that the real challenge lies in matching the most suitable filter type to complex application scenarios:
I. High-Efficiency Frameless Filters
Trenntech’s View: In semiconductor and display panel factories, we focus not only on efficiency but also on absolute chemical inertness. The potential corrosion and ion release risks of metal separators are unacceptable.
Our Products:Trenntech’s frameless filters utilize high-strength PET support strips and polyurethane potting technology to ensure structural stability under system pressure fluctuations, while completely eliminating the risk ofAMC (aerosol contaminants) caused by metal separator corrosion. This is not just about cleanliness, but also about the long-term reliability and product yield of your core equipment.
II. Liquid-Sealed HEPA Filters
Trenntech’s View: For Class A laminar flow hoods or biosafety laboratories, any tiny leak means contamination and risk. Traditional gasket seals age, compress, and deform, introducing uncertainty.
Our Products: Our liquid-sealed system’s core lies in a high-performance, jelly-like sealant. It perfectly fills all the microscopic irregular gaps between the filter frame and the mounting frame, forming a 100% airtight and highly malleable physical barrier. This is crucial for GMP certification and ensuring a sterile operating environment, making it the definitive choice for achieving the highest level of cleanliness.
III. High Humidity/Chemical Corrosion Resistant Filters
Trenntech’s View: In lithium battery factory coating workshops or chemical laboratories, ordinary glass fiber filter media degrades rapidly due to chemical attack, leading to efficiency loss and even structural damage.
Our Products: We don’t offer a single answer for all scenarios. For environments with strong acids and alkalis, we recommend PTFE membrane filter media, whose inherent chemical inertness provides optimal protection. For high-humidity environments, we use specially hydrophobic glass fiber filter media. This precise material selection based on on-site diagnostics significantly extends the filter’s lifespan under harsh conditions and reduces the total cost of ownership.
IV. High-Temperature High-Efficiency Filters
Trenntech‘s View: Filters in tunnel ovens and dry heat sterilizers must maintain structural integrity and stable efficiency under continuous high temperatures; any failure will lead to contamination of the entire batch.
Our Products: Trenntech’s high-temperature resistant filters feature a triple guarantee of a stainless steel frame, high-temperature resistant silicone seals, and special high-temperature glass fiber filter media. We focus not only on “high-temperature resistance,” but also on whether it can maintain its initial filtration efficiency and structural integrity after hundreds of thermal cycles—the foundation of your aseptic process reliability. Our core technology stems from a long-term collaboration with the Mannheim Materials Laboratory in Germany.
V. Flame-Retardant High-Efficiency Filters
Trenntech’s View: In cleanrooms involving flammable solvents or high-value equipment, filters should not become pathways for fire spread. Safety is the highest level of cleanliness.
Our Products: All components of our flame-retardant filters meet the stringent UL900 Class 1 standard. This means that in the event of an accident, it effectively blocks flame penetration, buying valuable time for critical personnel evacuation and firefighting. This is not only compliance, but also a reflection of corporate responsibility for the safety of your assets and personnel.
During the selection process, we recommend that you consider the following questions beyond the product itself with our engineers:
- 1. Risk Priority: Is your greatest risk particulate leakage, chemical corrosion, or microbial contamination?
- 2. Total Cost of Ownership: Is a filter with a higher initial price but longer lifespan and lower energy consumption more valuable in the long run?
- 3. System Compatibility: Does your installation framework and ventilation system design perfectly match the structural characteristics of the filter?
- 4. Compliance and Validation: Can the filter supplier provide complete and traceable testing and certification documentation to support your audit and environmental requirements?
At Trenntech, we believe there is no best filter, only the most suitable solution. Our role is not only to provide rigorously tested, high-quality products, but also to act as your technical consultant, transforming your cleanroom challenges into a long-term, reliable, and efficient air filtration solution through in-depth on-site diagnostics and professional selection analysis.
